Galvanized Steel Pipe Construction Tubes High - accuracy ERW Steel Square Tube Mill
ERW Tube Mill with Turks-head Forming Technique Introduction:
Advantage of Turks-head Forming Technique:
1. Save rollers: part of the molds can be commonly used. Especially for square & rectangular pipe.
2. The Turks - head can be rotated, so the welding seam can be put in any position of the pipes.
3. It can prevent the surface of pipe from scratching.
4. The max thickness of the round pipe and square pipe can be same. (The upper limit of thickness for square pipe is always 1 mm
less than round pipe's using round-to-square forming method)
5. The production shape is much better, the shape of square & rectangular pipe is very neat.
6. The Turks - head put 4 sides of force on the pipe at same time, which can reduce the wear and tear of the mill, protect the tube mill,increase the using life.

Square Tube Mill Details Images:
Forming Section
Function: to form the steel strips into a round shape and ready to be welded.
Advantage:
>Advanced forming technical
>One-stage molding platform
>Reliable quality gearbox
>Siemens Beide motor
Welding Section
Function: To weld the edges of the steel strips together by H.F. Welder (the H.F. Welder is not included).
Forming & Sizing Mill
Function: After welding, the pipes are almost the round shape, but it still needs to be modified into a regular round shape.
Company Introduction
FAQ:
Q:Are you manufacturer?
A:Yes,we are manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and
Moulding ). We also have our own R&D department. Welcome to visit us.
Q:What kind of payment term do you do?
A: We do T/T and L/C.
Q:What info do you need before giving me the price and proposal?
A: Since we design individual machine based on our customer's requirement, we need your desired
products' basic dimension, including all the pipe diameter(or tube length), thickness range , usage,
raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A:Contact us immediately ,we provide free consultant for pre-sales service .Also we can help you
solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q:How do you do QA?
A:We have special team to do strict QA,this is one of our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure its in the range of tolerance critical parts will be
inspected for all dimensions.
Q:Why I should choose you? what are the differences between you and other Chinese suppliers?
A:We are concentrate on pipe making machines for more than 20 years. We have constructed many
